BSP Layers and Reference Images for Yocto Project Issue Tracker

Description: Suspend/resume is broken on 0065 Verdin iMX8MP QuadLite.

Description: Randomly Bluetooth initialization might fail with `Bluetooth: hci0: FW Download Timeout` errors.

Description: Use a default (empty) wrapup.sh script for Apalis/Colibri iMX6. The old wrapup script did fuse/configure the SoC and eMMC for fastboot mode. Since 2017 Q2 this is the factory default so the configuration is already done. See the module revision history for exact version which included the change.

Description: Add a mechanism to dynamically detect the iMX8MM version and set up the correct CAN oscillator frequency.

Description: Update U-Boot to mainline v2024.07 for Toradex's upcoming BSP 7 release.

Description: Supports Ivy Carrier Board on Toradex's BSP: Linux Kernel and OpenEmbedded Reference Layers.

Description: Supports Ivy Carrier Board on Toradex's BSP: Linux Kernel and OpenEmbedded Reference Layers.

Description: Stop installing perf in our images by default.

Workaround: If you need 'perf' build a custom image in Yocto which adds perf back.

Description: Remove usage of `defargs`, `vidargs`, `setupargs` to change the Linux kernel command line from U-Boot (`tdxargs` is still present). In addition to the U-Boot `tdxargs` variable, the OpenEmbedded `APPEND` standard variable can now be used to change the Linux Kernel command line.

Description: Enable watchdog in U-Boot.

Description: TPM interrupt is not working, driver is working in polling mode, the driver fallback to polling mode with this error `tpm tpm0: [Firmware Bug]: TPM interrupt not working, polling instead`.

Workaround: TPM is working fine despite this issue, no known drawback when using polling mode and no firmware bug is present. Commit `e644b2f498d2 ("tpm, tpm_tis: Enable interrupt test")` from mainline kernel can be back-ported if needed.

Description: CPU frequency changes based on thermal trip points (passive cooling) is not working

Description: Add a mechanism to dynamically detect the iMX8MM version and set up the correct CAN oscillator frequency.

Description: Update SCFW to version v1.16, hash f407904f. * Add support for new part numbers: MIMX8QMnAVUFEAx (iMX8QM) and MIMX8QPnAVUFEAx (iMX8QP) with reduced A72 and GPU frequency * Ensure both GPU core and shader frequency are limited based on fuse.

Description: Merge U-Boot from TI Release 09.02.01.10

Description: The Verdin I2C_2 clock frequency was limited to 10kHz in the device tree to improve I2C communication for HDMI DDC. The limiting is now moved to the DSI to HDMI device tree overlay to have the full I2C speed available if using the I2C for something different from HDMI.

Description: Riverdi's 10" DSI display touch controller fails to report some events on the Verdin iMX8MM

Description: It's not possible to feed the AM62 watchdog from systemd using the RuntimeWatchdogSec setting. The module enters a boot loop when this setting is enabled.

Workaround: Apply patch https://lore.kernel.org/all/20240404153319.1088644-1-jm@ti.com/ to the Linux Kernel.

Description: Bluetooth connections and scan might fail with `Bluetooth: hci0: Frame reassembly failed` kernel errors.

Description: Occasionally, following a system reboot, is not possible to play/record audio on the sound card, despite the apparent normal functionality of the sound subsystem. This issue arises from a race condition within the kernel's audio driver controller.

Description: Some spurious ERROR messages are print at boot ``` ERROR: reserving fdt memory region failed (addr=9cb00000 size=100000 flags=4) ERROR: reserving fdt memory region failed (addr=9cc00000 size=e00000 flags=4) ERROR: reserving fdt memory region failed (addr=9da00000 size=100000 flags=4) ```

Workaround: These error messages can be safely ignored. Alternatively EFI could be removed from the U-Boot configuration.

Description: Verdin PCIE_1_RESET# (PERST#) line stays asserted on the AM62, which can cause problems with USB LTE modems connected to the mini PCIe connectors of our carrier boards.

Description: If UUU loads the boot container into RAM, failures may occur based on the container size with this error message `HID(W):LIBUSB_ERROR_NO_DEVICE`. A footer added to the binary in the uuu_bootloader_tag.bbclass file is unexpected by the BOOTROM during imx-boot download to RAM. When U-Boot download completes, BOOTROM initiates it. However, if the imx-boot binary size triggers a new USB package to begin with the appended footer, BOOTROM considers the transmission complete and starts U-Boot. Meanwhile, UUU, unaware of the completed transmission, attempts to send a new packet, resulting in an error. The issue can be reproduced when the binary file size minus 40bytes is a multiple of 1020 bytes.

Workaround: Remove the "stat -L -cUUUBURNXXOEUZX7+A-XY5601QQWWZ%sEND" from "uuu_bootloader_tag.bbclass" to prevent the appended footer and use the $UUU_BOOTLOADER binary instead of $UUU_BOOTLOADER_TAGGED.

Description: Starting from Verdin AM62 V1.1B HW Revision HSFS SOC is used and this change requires using a different firmware file. Previous HW variants will fail to boot after this change.

Workaround: Using old variants is still possible using the previous GP firmware ("tiboot3-am62x-gp-verdin.bin"). For example, the tezi JSON file can be edited replacing "tiboot3-am62x-hs-fs-verdin.bin" for the relevant product ids.

Description: Update Downstream TI U-Boot to TI release 9.02.00.009 based on U-Boot 2023.04.

Description: The native HDMI clock signal keeps running when a Hot Plug Detect disconnect event is received but the cable is still connected

Description: 0057 Verdin iMX8M Mini DualLite 1GB and 0060 Verdin iMX8M Mini DualLite 1GB WB IT has 32MB of CMA Memory configured instead of the intended 512MB.

Description: The CPU is always starting at 1.2 GHz, even on SKU with SOC that is rated maximum at 1.0GHz (PID4 0071 and 0072). Kernel warning: `cpufreq: cpufreq_online: CPU0: Running at unlisted initial frequency: 1200000 KHz, changing to: 1000000 KHz`

Workaround: No known malfunction is known because of this issue.

Description: Update Toradex TI U-Boot to TI Release 09.01.00.008

Description: In some specific condition modules using Micron MTFC4GACAJCN eMMC might get stuck during boot with the following error `mmc0: Card stuck in programming state! mmcblk0 card_busy_detect`.

Workaround: Apply patch `ed9009ad300c ("mmc: Add quirk MMC_QUIRK_BROKEN_CACHE_FLUSH for Micron eMMC Q2J54A")` to your kernel (https://lore.kernel.org/all/20231030224809.59245-1-beanhuo@iokpp.de/).

Description: USB Host interface is not working in U-Boot.

Workaround: apalis-imx8: execute `gpio set 132` before `usb start`

Description: Starting USB in U-Boot via `usb start` will lead to a crash and subsequent reboot: ``` Colibri iMX8X # usb start starting USB... Bus usb@5b0d0000: USB EHCI 1.00 Bus usbh3: XHCI-imx8 init hccr 0x000000005b130000 and hcor 0x000000005b130080 hc_length 128 Register 2000820 NbrPorts 2 Starting the controller USB XHCI 1.00 scanning bus usb@5b0d0000 for devices... 1 USB Device(s) found scanning bus usbh3 for devices...

Description: Add support for 0064 SKU

Description: Add support for 0065 SKU

Description: Booting a FIT image that includes a RAM disk is not working. Boot fails with the following errors: `Error: ramdisk overwritten`, `Ramdisk image is corrupt or invalid`.

Workaround: Update `UBOOT_RD_LOADADDRESS` in OE machine conf file.

Description: Using Iris / Iris v2 carrier board device tree and during the initial boot the kernel print some errors: ``` imx8qxp-pinctrl scu:pinctrl: pin IMX8QXP_QSPI0A_DATA1 already requested by scu:pinctrl; cannot claim for gpio-keys imx8qxp-pinctrl scu:pinctrl: pin-157 (gpio-keys) status -22 imx8qxp-pinctrl scu:pinctrl: could not request pin 157 (IMX8QXP_QSPI0A_DATA1) from group gpiokeysgrp on device scu:pinctrl gpio-keys gpio-keys: Error applying setting, reverse things back ```

Workaround: No know issues because of that. The pin is configured correctly and the error is showing that there is a duplicated configuration. The affected pin is still correctly configured and it is fully working as expected (SoM wake up source).

Description: U-Boot might prints some warning at boot complaining about "not owned" resources, e.g.: ``` Disable clock-controller@585a0000 rsrc 411 not owned Disable clock-controller@59580000 rsrc 512 not owned Disable clock-controller@5a4d0000 rsrc 62 not owned Disable clock-controller@5ac90000 rsrc 102 not owned ``` These warnings are a result of the resource partition checking when a device/peripheral is used by the Cortex-A (e.g. enabled in the dts file), but according to the SOC HW partitioning it's not supposed to be owned by it.

Workaround: Verify if this peripherals are supposed to be available and owned by the Cortex-A cores, if the answer is negative there is no issue and no action to be taken. Some peripherals might just not be available on the specific SOC making the whole warning messages just bogus.

Description: PCIe devices, including Wi-FI, are not always detected at boot, failure rate is about 5%.

Description: Enable HMP support on Verdin iMX8M Plus with dedicated dtb overlay.

Description: When using the “fsl,imx6sx-lcdif” (ADMA LCDIF DPI Interface) driver and rendering graphics using the GPU some display artifacts can happen.

Workaround: Set `use-g2d=0` in /etc/xdg/weston/weston.ini or Use DPU ( "fsl,imx-lcdif-mux-display" driver, display_lcdif) as a display controller.

Description: Add support for Verdin iMX8MP V1.1B

Description: Update Colibri iMX8x U-boot to version lf_v2022.04.

Description: Update SoC temperature threshold to IT values, passive = 95 °C and critical = 105 °C, lowering both the values by 22 °C.

Description: The NAND bad block table is getting corrupted at every boot because of a configuration mismatch between U-Boot (using OOB data for bad blocks) and Linux (using an in-band table at the end in the last 2 NAND blocks). This could potentially cause data loss in case a bad block is reused and the error is not recoverable with ECC.

Workaround: Set `CONFIG_SYS_NAND_USE_FLASH_BBT=y` in U-Boot configuration.

Description: Neither USB device nor host functionality is working in U-Boot.

Workaround: Stay on the U-Boot as shipped with the latest stable BSP 5.7.0

Description: Update to Linux Kernel v6.1

Description: Bluetooth interface might not be properly initialized at boot, the following errors might happen: `Bluetooth: hci0: command 0x1003 tx timeout`, `Failed to start discovery: org.bluez.Error.NotReady`

Description: There is a performance and boot time regression on initial BSP 6 releases compared to BSP 5, e.g. boot time on Apalis iMX6 increased from ~18seconds to ~30seconds, the reason is that some unwanted debug kernel configuration was enabled.

Workaround: Set `CONFIG_DEBUG_WW_MUTEX_SLOWPATH=n` or `CONFIG_PROVE_LOCKING=n` in the Linux kernel configuration

Description: Update TF-A (ATF) to version `v2.6(release):lf_v2.6-g9202efc9aa`

Description: Some monitor might not work (no display signal) or use a mode different from the preferred one using the HDMI interface, this is because video modes are filtered out if the monitor expected pixel clock is "too" far from the clock that the SOC is able to produce.

Description: The NAU8822 audio codec available on the Verdin development board cannot be configured in bridge-tied load

Description: Colibri iMX6ULL doesn't wake up from suspend if the ethernet interface is disabled when the system is put to sleep. With the ethernet interface enabled, suspend / resume works.

Workaround: Don't disable the ethernet interface if you need to sleep/resume. Otherwise, use BSP 6.1 or later, this issue is already fixed there.

Description: HMP Overlay on Verdin iMX8M Mini (RemoteProc and RPMsg) is not working.

Description: USB RNDIS supports is getting deprecated [1], move USB Ethernet-over-USB functionality to USB NCM, updating libusbgx configuration. Starting with Windows 10 this USB protocol is also available in Windows and it has been available in Linux for a long time. [1] https://lore.kernel.org/all/20221123124620.1387499-1-gregkh@linuxfoundation.org/

Description: PREEMPT_RT was not enabled by default on RT Downstream images

Workaround: PREEMPT_RT config depends indirectly on !KVM, so make sure that KVM is not set

Description: Update NXP downstream multimedia and graphics packages to version LF5.15.52_2.1.0

Description: Update downstream U-Boot to version LF5.15.52_2.1.0

Description: Some kconfig option required by some systemd functionality are missing in the kernel config, add those.

Description: Update Wi-Fi SDIO-UART W8997 Firmware from version 16.92.10.p219.5 (`mxm5x17283.p2`) to 16.92.21.p55.3 (`mxm5x17344.p3`)

Description: The default audio interface is not the analogue one

Workaround: Explicitly specify the required audio interface

Description: Bluealsa is not starting/working

Description: The Wi-Fi regulatory DB is not automatically loaded, because of that a limited number of Wi-Fi channels is available and the sample Wi-Fi AP configuration is not working out of the box.

Workaround: Manually reload the regulatory db: `iw reg reload` and `iw reg set `. Verify with `iw reg get`

Description: Wi-Fi connection is not stable, it stops working after less than a minute of stress testing.

Description: CAAM driver has some failure warning during boot (`caam_jr 30901000.jr: failed to flush job ring 0`, `caam_jr: probe of 30901000.jr failed with error -5`). JR0 is reserved for secure world usage and Linux kernel cannot use it.

Workaround: The error message is just cosmetic, no known issues.

Description: TF-A (ATF) updated to version `v2.6(release):lf_v2.6-g9202efc9aa`

Description: DSI-to-HDMI does not implement hot plug detect on event, a 10 seconds polling is used instead. Because of that timing could be incorrect when a different monitor is plugged in.

Description: VPU and video playback do not work.

Description: Initial support for Apalis iMX8 with U-Boot toradex_lf_v2022.04.

Description: Audio is played with the wrong sample rate (44100 vs 48000 Hz) on Verdin Development Board, a 6.5 seconds audio file plays in about 6 seconds (8% faster)

Workaround: Use 48kHz sample rate or set `simple-audio-card,mclk-fs = <256>;` in sound_card dts node.

Description: Under very rare timing circumstances, a data corruption might occur on a dirty cache line that is evicted from the L1 Data Cache due to another cache line being fully written, see ARM Cortex-A9 Errata 845369 for details. This could happen because `CONFIG_ARM_ERRATA_845369` is not enabled in U-Boot configuration. Enabling this errata has some effect on memory benchmark results, but it is not expected to have a significant impact on real applications.

Workaround: Enable `CONFIG_ARM_ERRATA_845369` in U-Boot configuration.

Description: Update Linux kernel for RT upstream distribution to version 6.0.0-rt11

Description: The SLEEP_MOCI# is not properly configured on the Verdin iMX8M Plus, because of that any carrier board relying on this signal could have malfunctions. CAN/PCIe and USB are not working correctly on Dahlia because of that.

Description: Remove `toradex-fitimage.bbclass`, use standard OE kernel-fitimage.bbclass instead

Description: Spidev is no longer enabled on base dts file, add a device tree overlay to enable the functionality.

Description: Spidev is no longer enabled on base dts file, add a device tree overlay to enable the functionality.

Description: Add support for 0058 Verdin iMX8MP V1.1B dual rank DDR RAM to BSP5.

Description: USB Host interface is not working in U-Boot.

Workaround: apalis-imx8: execute `gpio set 132` before `usb start`

Description: As per NXP errata ERR050805 (https://www.nxp.com/docs/en/errata/IMX8MM_0N87W.pdf), DRAM Controller automatic de-rating logic may not work when the LPDDR4 memory temperature is above 85ºC at initialization. The DDR Controller will therefore not automatically adjust the memory refresh rate or de-rate memory timings based on the LPDDR4 memory temperature. This may cause the controller incorrectly setting the refresh period, potentially cause the LPDDR4 memory losing data contents and lead to possible data integrity issues above 85ºC.

Description: Add support for 0070 SKU

Description: When using the “fsl,imx6sx-lcdif” (ADMA LCDIF DPI Interface) driver and rendering graphics using the GPU some display artifacts can happen.

Workaround: Set `use-g2d=0` in /etc/xdg/weston/weston.ini or Use DPU ( "fsl,imx-lcdif-mux-display" driver, display_lcdif) as a display controller.

Description: The NAND bad block table is getting corrupted at every boot because of a configuration mismatch between U-Boot (using OOB data for bad blocks) and Linux (using an in-band table at the end in the last 2 NAND blocks). This could potentially cause data loss in case a bad block is reused and the error is not recoverable with ECC.

Workaround: Set `CONFIG_SYS_NAND_USE_FLASH_BBT=y` in U-Boot configuration.

Description: The custom fstab that's installed on our builds doesn't include the "defaults" option that gets substituted by "to" as part of the openembedded "read-only-rootfs" IMAGE_FEATURE. Because of this, setting the image feature doesn't achieve the desired result of having the rootfs mounted as read-only.

Workaround: Patch the file meta-toradex-demos/recipes-core/base-files/base-files/fstab and include the "defaults" option: - /dev/root / auto noatime 1 1 + /dev/root / auto defaults,noatime 1 1

Description: On the Dahlia carrier board the Headphone volume is set to a default value after resume from standby or if nothing is played for more than 5 seconds.

Workaround: Restore the volume to the desired level after resume.

Description: RTC time is not properly restored on boot when using the Colibri iMX8X connected to an Iris V2 carrier board.

Description: Audio is played with the wrong sample rate (44100 vs 48000 Hz) on Verdin Development Board, a 6.5 seconds audio file plays in about 6 seconds (8% faster)

Workaround: Use 48kHz sample rate or set `simple-audio-card,mclk-fs = <256>;` in sound_card dts node.

Description: Update memory timing to ensure a more robust memory initialization on the whole temperature range

Description: It is not possible to drive the GPIO on pin SODIMM-178 of the Colibri IMX7 using the downstream BSP image.

Description: Add support for USB Host on Verdin iMX8M Plus.

Description: As concurrent use of SDIO Wi-Fi and Bluetooth is causing issues an alternative would be to use the UART for Bluetooth.

Description: If the Verdin iMX8MM receives at 1Mbits/s with around 100% bus load CAN frames with a 1 byte payload, around 15..20% of frames are lost.

Workaround: Set `spi-max-frequency = <8500000>;` in the device tree in `can1: can@0` node or update to version 5.6.0 or later. After that packet loss at 1Mbit/s with 100% bus load and 1 byte DLC payload is about 4%.

Description: The Verdin iMX8M Mini may crash during boot with the default configuration if the DSI to HDMI display adapter is NOT plugged in.

Workaround: Remove DSI to HDMI adapter overlay in case you do not have the adapter present (see also `skip_fdt_overlays`)

Description: Memtester update to version 4.5.1

Description: Drop discontinued Apalis iMX8X SOM

Description: Add FIO, Flexible I/O tester (https://github.com/axboe/fio)

Description: Booting with `fdt_overlays=apalis-imx8_mezzanine_lvds_overlay.dtbo display-lt170410_overlay.dtbo` the backlight of the 10" LVDS display is off.

Workaround: # echo 0 > /sys/devices/platform/gpio-fan/hwmon/hwmon0/pwm1
# gpioset gpiochip1 22=1

Description: In U-Boot the NAND storage is much slower compared to Linux (1MiB/s vs 30MiB/s)

Description: Lower CPU usage of rngd at startup

Description: Due to an Errata of the KSZ9131 PHY, one of the LEDs on the Ethernet connector is falsely lit up, even if the PHY is not connected.

Workaround: Be patient!

Description: Increase kernel partition size to 12MB for NAND based SOM

Description: The 0028 Apalis iMX6 Quad 2GB IT SoM may sporadically fail to boot in case the ambient temperature exceeds 70 degrees Celsius. The issue is likely caused by sub-optimum RAM timings. The issue is going to be resolved by a future software update (delivering updated RAM timings).

Workaround: Updating to BSP 5.4.0 or any newer release fixes the issue.

Description: The interactive U-Boot cfgblock create command wrongly always creates a ConfigBlock for the NAND rather than the eMMC version of the module.

Description: Enabling Dynamic DDR Calibration on Apalis and Colibri iMX6. http://git.toradex.com/cgit/u-boot-toradex.git/commit/?h=toradex_2020.07&id=eb6c58cb014022d45a880c1eb9761e5d6ce623c0 http://git.toradex.com/cgit/u-boot-toradex.git/commit/?h=toradex_2020.07&id=240223cd41a776d1ddba96ac7252aeb4b2ebdb90

[ 1912.202119] Micrel KSZ8041 30be0000.ethernet-1:00: failed to set led mode

Workaround: Cosmetic problem. Nothing needs to be done.

Description: USB_1_EN signal gets enabled during kernel boot. This leads to the USB power switch being enabled, hence sourcing the VBus voltage. This leads to the board being powered by USB Client, even when unplugging the power to the Verdin Development Board. This ticket is about fixing this in software, so USB_1_EN is not high when in client mode.

Description: The assigned MAC address is not the same in U-Boot and Linux kernel.

Description: Deploy and automatically select the correct device-tree for Apalis iMX8 QuadPlus variants.

Workaround: The device trees are existing. Build them from the kernel source branch toradex_5.4-2.3.x-imx and deploy manually. In U-Boot you can select the device tree with fdtfile variable.

Description: Add device trees for all SKU variants and Carrier Boards of the Colibri family.

Description: When trying to resume an apalis-imx8 with WAKE1_MICO# signal it does not wake up and the module freezes. It seems to crash on resume.

Description: CMA memory allocation is a fixed value and takes up too much space on certain SKUs. Drop the configuration of the CMA in the device tree in favour of specifying it in the kernel config with a size of 256MB or 12% of total memory which ever is less.

Description: For native HDMI the pixelclock is provided by the a PLL in the HDMI PHY. The driver for the HDMI PHY accepts only modes with a pixelclock which matches a list of driver provided frequencies. This masks out EDID modes with one of these not compatible frequencies. Change the driver, so that it offers the closest frequency and change the bridge driver to accept also not exactly matching ones.

Description: Integrate new SCFW v1.7.3 that was released with NXP BSP L5.4.70_2.3.3 patch release.

Description: We may violate the on-module PHY reset timing and attempt communication with the PHY after resume while the PHY is still held in reset.

Workaround: In device tree delay the voltage regulator coupled to the fec/phy

Description: Integrate all the changes into our buildsystem/userspace which were released in NXP L5.4.70_2.3.2 patch release.

Description: Software reboot may stall 1.5 minutes stopping Weston Wayland compositor.
Stopping Weston Wayland Compositor...
[* ] (1 of 2) A stop job is running for …ayland Compositor (13s / 1min 31s)
This does not always happen. Not sure whether it depends on how long the session was already active.

Workaround: Just be patient (;-p).

Description: Real Energy Efficient Ethernet with Tx LPI (only supported on the on-module EQOS based MAC) may cause issues with EEE enabled peers/switches and is therefore disabled in NXP's BSPs. While NXP may have patches to fix this we also just disable it for now.

Workaround: Disable EEE either on the peer/switch side or on the module as follows:
ethtool --set-eee eth0 eee off

Description: Add support for HDMI (both native as well as via DSI-to-HDMI display adapter) on Verdin iMX8M Plus V1.0B.

Description: Add support for Ethernet on Verdin iMX8M Plus V1.0B.

Description: Add support for ADC on Verdin iMX8M Plus V1.0B.

Description: Change the default back to Vesa VGA timings for Colibri modules

Description: Drive strength settings were 87 Ohm at 3.3V and 50 Ohm at 1.8V. For impedance-matching, we need to set it to 50 Ohm at 3.3V and 30 Ohm at 1.8V.

Workaround: You may also find the patch fixing this here:
https://lore.kernel.org/patchwork/patch/1389632/

Description: Add support for the temperature sensor TMP75C available on Dahlia V1.1A and later.

Description: The following crash can be observed during system reboot:To reproduce please type, reboot command and check for trace from weston ........

Description: There is no output on the parallel RGB port which affects the operation of 7 inch capacitive and resistive touch panels.

Description: Support the Nuvoton NAU88C22YG audio codec found on the Verdin Development board V1.1A and later.

Description: An image for Apalis iMX8 contains in addition to the ones specific to Apalis iMX8 the specific ones for Apalis iM8X. While this does not hurt it might be confusing.

Workaround: -

Description: Creating a configblock with 'cfgblock create' in interactive mode the module Colibri iMX8DX 1GB WB cannot be set.

Workaround: Use cfgblock create with barcode information e.g. 'cfgblock create 0051100012345678'

Description: Change OpenEmbedded recipes from Toradex to fetch from https instead of git where possible.
In an approach to make it more user-friendly, especially for big company customers that do not allow git-protocol in their networks we decided to use https as a fetching source.
We are aware that we cannot do this for each and every layer but at least for ours we decided to switch from git to https.

Description: The XDG_RUNTIME_DIR variable required for graphical Wayland/Weston output is not set in an SSH shell.

Workaround: Use the local serial console instead.

Description: USB switches its role-state from client to host, client works but host does not enumerate plugged in devices.

Workaround: None

Description: Add the possibility to U-Boot so that it is possible to skip the loading of overlays set the environmen variable skip_fdt_overlays = 1

Description: Add missing display device tree overlays.

Description: Add missing display device tree overlays.

Description: On certain modules USB Host does not work correctly and outputs an endless error "usb 3-1: device descriptor read/all, error -71"

Workaround: Use the adjusted pinmuxing for USB-HSIC &usbh1 node in devicetree from most recent images. http://git.toradex.com/cgit/linux-toradex.git/tree/arch/arm64/boot/dts/freescale/imx8-apalis-v1.1.dtsi?h=toradex_5.4-2.3.x-imx#n1192

Description: The eMMC command queuing feature is broken in NXP BSP L5.4.70_2.3.0. Therefore, we had to disable it to avoid any corruption.

Description: Make sure PCIe works for 5.4.x-2.1.0 kernel.

Description: Add support for audio to the new 5.4.x-2.1.0 kernel.

Description: Symlinks linking to ADC inputs are missing.

Description: WIC images fail mounting /boot. Looks like classes/image_type_tezi.bbclass in meta-toradex-bsp-common is setting the label to all upper-case BOOT while WIC images are using all lower-case boot. This is particularly bad on Verdin iMX8M Plus as due to no Toradex Easy Installer being available as of yet we are using WIC images with the bmap tool for production flashing.

Description: Use unified /dev/apalis-emmc symlinks for fw_env.config so we only need one config for all modules.

Description: Make sure to document on our developer website which display interfaces are used by default.

Description: Make sure the boot partition on eMMC-based modules is mounted consistently across all modules to /boot.

Description: The Apalis iMX8 HDMI has problems with some display resolutions. This ticket solves the issues.

Description: The RTC on the Verdin iMX8 needs additional configuration to keep running on the backup battery voltage on power outage. It will be configured as the default.

Workaround: There are no workarounds, you must wait until this is implemented. Please contact us if you need this feature with urgency.

Description: Add initial support in U-Boot.

Description: Add support for VPU on 5.4-2.1.x kernel.

Description: NXP i.MX 8QXP/8QM-based modules the buildinfo shows some garbage instead of IMX-MKIMAGE version used.

Description: LPSPI occasionally receives wrong data.

Workaround: NXP’s L5.4.47-2.2.0 release seems to have this fixed on their i.MX 8QuadXPlus Multisensory Enablement Kit (MEK).

Description: Sending Data to ttyLP2 leads to endless loop.

Description: Kernel stuck at enumerating PCIe on Colibri iMX8X non-Wi-Fi modules.

Workaround: In U-Boot enter 'setenv tdxargs initcall_blacklist=imx6_pcie_init && saveenv'.

Description: On NXP i.MX 6ULL and i.MX 7 based modules the qt-demo is not working due to the missing qt-wayland backend. Fix this.
